When we were sophmores he was learning Lisp, which was greek to me. ("What the heck is a lambda?!") Two years later, Lisp was my favorite language.
By then, he was learning Haskell, which I could barely stand to look at. ("What the heck is a comprehension?!") Today, I love Haskell too.
Why am I telling you all this? Because that guy is into Factor now, though it's still total gibberish to me.
